PSU At Floor of Case

Gibbo3771 · 17 Jan 2013 at 17:26

Hi,

Just recently bought a new case and the layout puts my PSU at the bottom of the case rather than the top, well this was pretty good since it seems like a better idea anyway but yeah...I have a big fan on my PSU but it faces the floor...

There is however mesh grid on the entire floor of the case as well, suggesting that it would be ok.

Think this is safe? its a 650w OCz ZSseries PSU, case unknown.

if there is no filter for the psu intake then see if the case allows you to mount the psu there with the fan facing into the case.

Filter?

Can't have it with fan facing it, literally screw holes are off by a mile but its drillable but would rather avoid that due to warranty

Its perfectly normal to have the fan facing down, just look at the rigs in the case forum for proof.

Yes that is what the mesh grid is there for.

AHHHHH the PSU does not lie directly on the floor of the case, there is at least a 15mm gap. Guessing if its designed that way it's safe, cheers.

Think about it, if the fan was facing in the psu would be exhausting hot air into the case...not good.

With the psu fan facing the case floor, it draws in cool air from the mesh vents in the floor and expels it out the back of the psu.

Bottom mounted psu's are the norm now. Though there are some cases that offer the option of both top and bottom mounting.

Yep, it didn't seem logical if the fan was directly sitting on the metal though, due to poor ventilation and vibration but did not spot the gap hehe.

Just make sure you don't put the PC on a thick, deep-pile carpet.
